Potential energy surfaces near intersections
Webto calculate the potential energy surfaces of the five low-lying electronic states 1A 1, A 2, 3A 2, 1B 2, and 3B 2 of carbon dioxide molecule. Topology of intersections among these five states has been fully analyzed and is associated with double-well potential energy structure for every electronic state. WebRecent computational as well as experimental studies have produced ample evidence that the so-called conical intersections of electronic energy surfaces, predicted by von Neumann and Wigner in 1929, are the rule rather than the exception in polyatomic molecules.

Web11 Jun 2024 · Conical intersections between electronic potential energy surfaces are paradigmatic for the study of nonadiabatic processes in the excited states of large molecules. However, since the corresponding dynamics occurs on a femtosecond timescale, their investigation remains challenging and requires ultrafast spectroscopy techniques. Web6 May 2024 · The PES of BH is plotted with respect to B–H bond length in picometers. The PES of C 2 H 2 is plotted with respect to the HCC bond angle in degrees. The H–C and C–C bond length in C 2 H 2 are fixed at 110 and 132 pm, respectively. 6–311+g* is used as the basis set for QE-DFT calculations.
